Setting Boundary Conditions and Values
The heated fin consists of an inverted “T” shape placed in a closed box. The only boundary specifications required for this analysis are wall thermal conditions.
Apply a fixed temperature of 343 K to the base of the solid fin to provide the heat source. Set the vertical sides of the fluid-containing box to a fixed temperature of 293 K. All other wall boundary conditions are considered to be adiabatic. Use a contact-type conducting boundary at the solid-fluid interface.
Start with the wall boundary definitions for the fluid region.
- Navigate to the node.
-
Select the
Thermal Specification node and set
Condition to
Temperature.
The temperature value for this boundary can now be set.
-
Select the
node and set Value to 293 K.
The conditions for the Horizontal-Walls boundary (upper and lower walls of the fluid region) can remain at the default adiabatic setting.
You can now set the solid wall boundary conditions and values in a similar way to those of the fluid.
- Navigate to the node.
-
Select the
Thermal Specification node and set
Condition to
Temperature.
The temperature value for this boundary can now be set.
- Select the node and set Value to 343 K.
- Save the simulation.
